Title: Isotope separator
Inventor: KUWAKO AKIRA
IPC: B01D59/34
Filed: 1986-11-12
Abstract: PURPOSE:To enhance the separation efficiency of isotopes in an apparatus wherein the isotopes are selectively excited with laser beams, and ionized isotopes are separated by providing a fluorescence measuring apparatus sensing fluorescence which is generated when the atoms of excited isotopes are transited to the ground state. CONSTITUTION:Laser beams 9 are applied to a vapor flow 7 of a metallic raw material contg. a plurality of isotopes and the specified isotope is selectively excited, separated and recovered as the ionized isotope with electrodes 10 for recovering a product. On the other hand, one part of the nonionized vapor flow 7 is introduced into the front face of a fluorescence converging apparatus 14 and irradiated with branched lasers 20 and the specified isotope incorporated in the vapor flow 7 is selectively excited. One part of the excited isotope is transited to the original ground state and generates fluorescence when the lifetime elapses. This fluorescence is sensed by the fluorescence converging apparatus 14, and the wave shape is analyzed and transmitted to a wavelength controller. The wavelength controller calculates the deviation of generated fluorescence amount from standard value, and a signal regulating the wavelength in the direction to dissolve the deviation is output to a laser beam oscillator.

Title: Surface-shape measuring apparatus
Inventor: SAKUTA SHIGERU
IPC: G01B7/00
Filed: 1991-10-17
Abstract: PURPOSE:To obtain a surface-shape measuring apparatus wherein instability in measurement, measuring errors and the like due to the nonuniform expansion and contraction of a magnetostrictive element do not occur. CONSTITUTION:The coil part of measuring tip, through which a tunnel current flows, is idly inserted into a magnetostrictive element in a coaxial pattern. The surface shape of a body to be measured is obtained based on the displacement of the magnetostrictive element caused by a magnetic field, which is formed at the coil part of the measuring tip. Even if the tunnel current is very weak, the apparatus is not affected by the noises caused by the electric circuits of a control system. The surface shape of the body to be measured 1 can be obtained highly accurately and highly efficiently. Especially, since the coil part 13 of the measuring tip 3 is idly inserted into the magnetostrictive element 8 coaxially, the magnetic field within the range of the cross section of the magnetostrictive element 8 becomes uniform. As a result, the magnetostrictive element 8 is contracted uniformly at any part with respect to the fluctuation of the magnetic field. Furthermore, the magnitude of the magnetic field can be changed by changing the winding number per unit length, and the reliability of measurement is stabilized.

Title: Detecting method of polishing ratio of semiconductor wafer surface, detecting equipment, polishing method of semiconductor wafer surface and polishing equipment
Inventor: YANO HIROYUKI
IPC: B24B37/005
Filed: 1995-10-17
Abstract: PURPOSE: To detect the end point of a desired amount of polishing when a semiconductor wafer surface is polished, by using not the test polishing but the semiconductor wafer to be polished itself, without detaching the wafer from an equipment. CONSTITUTION: A wafer 14 to be polished is made to descend while being rotated, and comes into contact with an abrasive pad 13. An exposed surface part of the abrasive pad 13 is irradiated with an X-ray beam from an X-ray radiation tube 22. The intensity of X-ray fluorescence obtained by irradiating the pad with the beam is detected by a spectrometer 23. Since both the CMP elimination ratio of the wafer surface and the intensity of X-ray fluorescence are the functions of concentration of abrasive particles in slurry, the CMP elimination ratio can be shown by the function of the concentration. By using the intensity of the X-ray fluorescence detected by the spectrometer 23, the CMP ratio can be operated with an operational circuit 24.

Title: Color blur correction circuit
Inventor: KONO MICHIO
IPC: H04N9/83
Filed: 1991-09-19
Abstract: PURPOSE:To correct a color blur caused by a band limit of a chrominance carrier signal by increasing a side band signal component reduced by a band pass filter circuit with a mixing means. CONSTITUTION:A component of a chrominance carrier signal of an output signal S6 of a limiter circuit 6 is reduced by a trap circuit 8 comprising capacitors C1, C2 and coils L1, L2 and a side band component is extracted. Then the component is amplified by an operational amplifier 7 and its output signal S7 is given to a mixer 12, in which the signal is mixed with an output signal S4 from a 1st band pass filter 4. The mixed signal S8 is outputted from a terminal 13. Thus, since the signal component of the side band lost by the 1st band pass filter 4 for the band limiting is increased by the mixer 12 based on the side band signal component S7, the band of the chrominance carrier signal is spread and occurrence of blur at a border of video images is prevented.

IPC: G06F3/12
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To transfer received data in a confidential transmission way to even an output device that cannot produce an image by receiving printer codes. SOLUTION: Reception of an incoming call is started (S1), and when no SUB is in existence (NO in S2), its own machine provides an output (S3), and when the SUB is in existence (YES in S2), a confidential BOX management table is retrieved. When a confidential BOX coincident with the SUB is not available (NO of S4), the incoming call is rejected (S5), and when a confidential BOX coincident with the SUB is available (YES of S4), a received file with a BFT format is stored. After the end of reception, in the case that the confidential BOX with an F code coincident with the SUB registers no transfer destination (NO of S6), its own machine provides an output (S7). When the transfer destination is registered (YES of S6), a transfer type of the confidential BOX having the F code coincident with the SUB is checked (S8).  In the case of transferring printer code, the printer code part is transferred (S9), the printer image is transferred. In the case of ail transfer, an image is generated from the printer code and transferred (S10, S11).
